Hello, Here is how I combine shipping 2.99 for the first item and 1.00 for each additional item. Please include all item #'s with the payment as well. If you buy 5 or more sets I ship for a flat 5.00 and You must make a combined payment for all items as well. If you win 10 or more items shipping is free. International shipping is 3.50 for the first item and 1.00 for each additional item but if you buy 5 or more shipping is a flat 5.00 for the order. Thanks, Shane
